- What it's about
The Court decided Louisiana v. Callais on April 29, 2026, affirming and remanding a ruling that struck down Louisiana's SB8 congressional map as an unconstitutional racial gerrymander. The Court held that Section 2 of the Voting Rights Act, properly construed, did not require Louisiana to create an additional majority-minority district, so the state had no compelling interest for using race to draw District 6.
Question presented
Does Louisiana’s creation of a second majority-Black congressional district constitute unconstitutional racial gerrymandering, even when drawn in response to a federal court finding that the state’s prior single majority-Black district likely violated Section 2 of the Voting Rights Act?

Decision
What the Court decided
Louisiana's second majority-Black congressional district was unconstitutional because federal law did not require it.
Impact
Louisiana voters, especially Black voters in challenged District 6, are directly affected. The Court ruled that District 6’s race-based drawing violated equal protection (constitutional guarantee of equal treatment). For example, a District 6 voter cannot be placed chiefly by race without a compelling interest. Future claims under Section 2 (Voting Rights Act rule) must show intentional discrimination. Courts must distinguish racial divisions from partisan or other race-neutral factors.
